Growth of ZnO nanorods by aqueous solution method with electrodeposited ZnO seed layers

---

Abstract.
ZnO nanorod arrays on ZnO-coated seed layers were fabricated by aqueous solution method using zinc
nitrate and hexamethylenetetramine at low temperature. The seed layers were coated on ITO substrates
by electrochemical deposition technique, and their textures were dominated by controlling the
deposition parameters, such as deposition potential and electrolyte concentration. The effects of the
electrodeposited seed layers and the growing parameters on the structures and properties of ZnO
nanorod arrays were primarily discussed. The orientation and morphology of both the seed layer and
successive nanorods were analyzed by using X-ray diffraction (XRD), SEM and TEM. The results show
that the seed layer deposited at -700 mV has evenly distributed crystallites and (0 0 2) preferred
orientation; the density of resultant nanorods is high and ZnO nanorods stand completely perpendicular
onto substrates. Meanwhile, the size of nanorods quite also depends on the growth solution, and the
higher concentration of growth solution primary leads to a large diameter of the ZnO nanorods.
